Food Chain - Ecosystem
In a food chain, the food energy is transformed from a given source through a series of species, each of which eats the one before itself in the chain.

Sun → grass → goat → man
Each transfer a proportion of the food, energy is lost as heat. This limits the number of links or steps in a food chain, usually to four or five. In aquatic ecosystems, microscopic green plants called phytoplankton and algae play the same role as grasses in a pasture or trees in a forest.
